Equalization charging function

Maximum PV input voltage – 450VDC

Works with battery or without battery

Optional WIFI/ GPRS remote monitoring

Support parallel operation for capacity expansion up to 21kW

PV and Grid power the load jointly if PV energy insufficient

Flexibly schedule the Inverter charging and discharging time

1. Industrial-grade master chip, 16 AD sampling accuracy, temperature, charging current,
discharge current accurate real-time display, power generation at a glance.
2. Automatic focusing MPPT tracking charging, high charging efficiency, non-stop detection
during charging, bidirectional focusing tracking.
3. Large-screen LCD display, adjustable charging and discharging parameters. UItra-wide charge
and discharge adjustable, as long as you understand the characteristics of the battery set its
corresponding charging parameters, you can charge a battery. When the output is off, the time
can be adjusted, which is more convenient. (on the market, there is no point adjustment)
4. Acomplete three-phase charge management, effectively protect the battery, the battery is more
durable.
5. Built-in overheating, overcurrent short circuit, open circuit protection, reverse connection
protection,when the fault is eliminated, the controller automatically recovers, does not damage
the device.
6. Bidirectional MoS tube anti-backflow circuit, high-power charging mode, ultra-low heat.
7. R5. 0 solar charging DC plug, R5. 0 DC lamp output DC plug, convenient connection.
